Does your potty trained (or in training) lo pull pants down/up?

I am curious to find out how many little ones can do this on their own. My DS goes to preschool and right now he is in a class with a lot of almost 3 yr olds or just turned 3 and I see them go to the potty by themselves...no teacher.

DD can pull them down and up by herself but she often asks for help.¬† She usually dosn't go potty by herself because she likes to talk to us while she goes and she still needs some help wiping and turning on the faucet to wash her hands (can't quite reach yet).

Ava is starting to be able to get her pants down. She can undress herself and get her self dressed. She's been potty training for a little over a month now and is doing great! I think it'll take a bit for her to be able to get her pants down by herself.

Just undies, he can do it by himself no problem, but it really depends on the type of pants/shorts he is wearing as to whether he can get everything off (he refuses to pee or poop with pants at ankles, they have to be all the way off, lol). ¬†At home he goes pee by himself about half the time.

DS is starting to potty by himself- he can get elastic waist pants & pull-ups up & down without assistance; any pants with fasteners he can pull up but when they don't stay up will tell you they are "broked"

Adam can sometimes, it totally depends on which pair he is wearing along with what clothes he is wearing.¬† Most of the times he asks for help while pulling his undies up and down.¬† I figure its all good though that way i can be sure he is clean when he is done.

LO still asks for help getting her panties up/down. At home she often takes them off and go bare tush so she doesn't need help. she wipes pee on her own (almost too well) but I wipe for poop. She's been PL'ed since 22mo.
